Typing books or courses for teens

I'm not sure if this is the right place but want to teach my teenagers the "official" way to type. Any ideas out there?
Thanks.

I know this is an older message, but thought I would reply. I taught in a computer lab and we used Sunburst Type to Learn to teach typing. I use Typing Instructor at home, mainly because my kids had already worked on Sunburst. Both target what keys the kids miss and work on those keys. They have to score a certain percent before moving on. On Sunburst you can set the goals for your kids. Hope that helps.
